The Most Important Principle
The Wall is not a race you train for with sub-3-hour marathon preparation. You need your body โ feet, tendons, joints and mind โ to be capable of being on the move for 20โ27 hours. Long days and consistent weekly volume are the foundation. That said, training is highly individual โ your experience, goals and injury history all determine what the right approach looks like for you.
Key Training Elements
Time on Feet
The time-on-feet principle is central to Wall preparation. Build your long run progressively through your training block, targeting roughly marathon distance (26 miles / 42km) as your longest single effort, ideally 2โ3 weeks before race day. After that, taper progressively โ reduce your weekly mileage each week so your legs are genuinely fresh at the start line, not carrying accumulated fatigue from a hard training block.
Your peak training week should aim for around 60โ70 miles across all your runs and hikes combined. This is roughly the race distance across the week โ not in a single session.
A popular format: a long run in the morning followed by a long hike or easy run in the afternoon on the same day. This combination of running fatigue and walking volume is excellent Wall-specific preparation. Remember: what's right for one runner isn't right for another. Training should match your experience, goals and schedule.
Strength & Conditioning
Multiple experienced Wall runners specifically mention strength and conditioning as a race-saver. It comes up consistently in post-race reflections โ both from those who did it and those who wished they had.
Focus on: glute strength, single-leg stability (step-ups, single-leg squats), calf raises for descents, and core work. Strong hips and glutes protect your knees and ankles over 70 miles of varied terrain.
Night Training Runs
Night training runs get unanimous agreement in the community. Running in the dark feels fundamentally different to daytime running โ your pace drops, your mind plays tricks, and the psychological challenge is real. Being familiar with running in the dark before race day makes a huge difference.
Practice with your headtorch on terrain similar to The Wall's second half.
Gut Training
Train your gut to handle food while running. This is a specific, trainable skill. Practice eating every 20โ30 minutes on your long runs โ gels, real food, snacks โ so your digestive system adapts to processing calories while your body is working hard.
Race day is not the time to discover you can't handle gels at pace. Find out what works for your stomach during training, not during the race.
Train in Your Full Kit
Practice with all your kit and know how to use it โ this is among the most repeated advice from experienced Wall runners. Your vest loaded with water and food, your poles, your rain jacket, your mandatory kit โ all of it. Kit that feels fine empty feels very different after 6 hours with 2 litres of water, layers and snacks inside it.
Back-to-Back Long Days
Once or twice in your training block, do two long efforts on consecutive days. A very long run Saturday + long hike Sunday. This teaches your body to function when already fatigued โ which is exactly what The Wall demands from mile 40 onwards. Recovering while still moving is a learnable skill.
Pace Planning & Target Finish Times
The Wall is 70 miles / 112.65 km. Use this table to understand what average pace you'd need to maintain to hit your target finish time. These are overall averages โ in practice you'll be quicker in the first half and slower in the second, and you'll be spending time at pit stops too.

|---|---|---|---|
| 10 hours | 8:34 /mi | 5:20 /km | Elite โ top 10 finish, running nearly throughout |
| 11 hours | 9:26 /mi | 5:51 /km | Very strong โ top 20%, sustained running pace |
| 12 hours | 10:17 /mi | 6:23 /km | Strong โ mostly running with walking on hills |
| 13 hours | 11:09 /mi | 6:55 /km | Good run/walk mix throughout |

| 15 hours | 12:51 /mi | 7:59 /km | Run/walk mix, brisk on the flat sections |
| 16 hours | 13:43 /mi | 8:31 /km | Mix of jogging and power hiking |
| 17 hours | 14:34 /mi | 9:03 /km | Power hike with some running on easy ground |
| 18 hours | 15:26 /mi | 9:35 /km | Consistent power hike pace |
| 19 hours | 16:17 /mi | 10:07 /km | Solid walking pace with occasional jog |
| 20 hours | 17:09 /mi | 10:39 /km | Brisk walk throughout โ 3.5 mph average |
| 21 hours | 18:00 /mi | 11:11 /km | Steady walking pace โ 3.3 mph average |
| 22 hours | 18:51 /mi | 11:43 /km | Comfortable walking pace โ 3.2 mph average |
| 23 hours | 19:43 /mi | 12:15 /km | Easy walk pace โ ~3.0 mph average |
| 24 hours | 20:34 /mi | 12:47 /km | Slow walk โ within cut-off but with little margin |
| 25 hours | 21:26 /mi | 13:19 /km | Very slow โ within cut-off for earlier wave starters |
| 26 hours | 22:17 /mi | 13:51 /km | Race cut-off (09:00) for latest wave (07:00 start) โ barely a walk |
Based on 70 miles / 112.65 km. Cut-off is 09:00 Sunday regardless of start wave.
Mental Preparation
The Wall will test your head as much as your legs. The community is very clear on this.
The dark moments are normal. Every Wall runner experiences them. The difference between finishers and DNFs is often just the knowledge that dark moments pass โ they always do.
Break the race into sections. When it gets hard, focus only on reaching the next landmark โ the top of a hill, the next village, the next checkpoint. Don't think about the finish, just the next thing. Before you know it you'll be there.
Talk to people. From 2-minute chats to 2-hour conversations โ all vital for motivation. Wall runners consistently report that talking to strangers on the course does wonders for morale, especially through the dark sections.

How many miles a week should I be running?
The community focus is on time on feet rather than a specific mileage number โ but a sensible framework is building to a peak week of around 60โ70 miles (running and hiking combined) in the 4โ6 weeks before your taper. Your longest single run should reach around marathon distance, completed 2โ3 weeks before race day.
After your peak week, taper progressively โ reduce volume each week so your legs arrive at the start line recovered and ready. Don't be tempted to cram more miles in the week before the race. Fresh legs beat tired ones every time. What's right for your training depends on your experience, goals and injury history โ a structured plan or coach makes a big difference if you're new to ultras.
Should I walk during training?
Yes, absolutely. The Wall is an ultra โ most people will be walking significant portions of it, particularly the hills. Practice walk-running in training. Learn your "power hiking" pace. Walking isn't failure, it's strategy โ and doing it in training means you're comfortable with it on race day.
The community's most-liked single piece of advice was simply: "Walk the hills." This applies equally to training. Get comfortable with power-hiking in training so it feels natural on race day.
How do I train for the night section?
Do at least a few night runs during your training block. They don't need to be all-nighters โ even a 2-3 hour run starting at 10pm or 11pm teaches your body to function when it wants to sleep. Use your headtorch, run the kind of terrain you'll face on The Wall, and practice eating in the dark. The psychological experience of running through the night is very different to running in the day.
Should I use a training plan or coach?
Having a structured plan removes daily decision-making and ensures you build progressively without overdoing it. Many established ultra training plans exist online (Hal Koerner, Jason Koop) โ or hire a coach if budget allows. The Wall Facebook community also has experienced runners who offer informal advice. The key is consistency: a decent plan followed well beats a perfect plan followed badly.
Should I pause my GPS watch at pit stops?
No โ never pause your watch during the race. The race clock does not stop when you are at a checkpoint, eating, sitting down or having a rest. It runs continuously from your wave start until you cross the finish line. Your watch should do the same.
If you pause your watch and forget to restart it โ which is very easy to do at 3am after 18 hours on your feet โ your recorded elapsed time won't match the official clock, and you'll have no idea how much time you've spent stopped. Worse, you might find you've lost an hour of data and have no way of knowing your real pace or time left. Keep the watch running throughout. Seeing elapsed time ticking up while you're at Hexham is actually a useful reminder to keep your stop short.
